is burnt out. \u003cbr\u003e2.When MCU-51 P0 port controls, the pull-up resistor must be connected, and the suggested resistance is about 4.7K-10K. \u003cbr\u003e3.Please insert the dot matrix to the round hole block firstly, and then insert the round hole block to the PCB board for weing. \u003cbr\u003e4.Please hold the side of dot matrix with words towards yourself, and the PIN of this side is on the order of 12345, from left to right. \u003cbr\u003e\u003cbr\u003eDownload-Link: \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"a-list-item\"
